HERBERT A.VCHU'RCH, OF NEWYRK;

"nr einer 1 GASJVAPOREIZER.

Be'. it known that; I, I-Inannr A.. CHURCH,

a.. citizenofrthe United. States, residing at Grary Mills,- in. thecounty of St. Laiv- 5 renceand.State.of Newl York, have invented certainnew andl useful Improvements in GasVaporize-rs,.of which the followingis at specification..

Thisinvention relatesV to improvements .in fuelatoniizers,designed forAuse` in connection with internal. combustion engines,` and hasl foritsobject to provide'noveland simple means for reatomizing the explosivemixture: after it. has.. passed fromthe carbureter: towards the-I enginecylinders.

At the present time, the explosive gas which effects the driving ofautomobiles, and the like, is drawn by the suction of the pistons fromthe carbureters, usually through needle-valves, which atomize thegasolene, and the latter is mixed with air in varying proportions beforeit reaches the compression chambers of the engines. This explosivemixture is usually carried to the cylinders through a common intakemanifold, which is arranged to supply the cylinders individually. Thedistance the mixture has to travel from the ordinary mixing chamber,near the carbureter, to the several cylinders varies greatly, and it hasbeen found that during this passage there is a tendency for the gas tobecome more or less condensed before it is finally exploded. This isespecially true of the more remote cylinders, which accordingly receivethe vapor in a coarser state than the nearer cylinders, and thereforeyield correspondingly less power. Furthermore, owing to the fact of thisimperfect vaporization of the explosive element, a considerable portionof the gasolene passes through the engine unconsumed.

A particular object of the present'invention is primarily to savegasolene and therefore get more car mileage from each gallon ofgasolene, by providing means for revaporizing the 'explosive mixture.This is accomplished by disposing a number of simi` lar adjustableatomizing members in the several passages through which the gas flowsfrom the usual mixing chamber to the engine cylinders. ment, theseauxiliary atomizers are disposed In the preferred arrangea face` view of the adjustable wing carried by each spherical body. Fig isa modifi-Vcation ofthe means for holdingA thel balls in place.

In the drawing, 2 represents conventionally a gas engine. 3 is thecarbureter, and 4 is the usual intake manifold, which conducts theexplosive mixture from the carbureter to the engine cylinders, the twodischarge arms of the manifold being indicated at 4 and 4a. My improvedatomizers preferably consist of similar spheres or balls 5, which may bemade of any suitable metal.

For the ordinary manifold 4, I prefer toV employ two or more of thespheres 5, one being preferably disposed in the open end of each of thearms 4 and 4a, at the nearest point to the cylinders 2', as best seen inFigs. 2 and 3. The balls 5 are perforated diametrically and arepreferably threaded to receive the threaded portions of bolts 6, whichpass through the arms of the manifold, the latter being threaded at oneside tohold the bolts in place. By this construction and arrangement,the balls 5 may be adjusted and set in different positions relatively tothe bore of the arms 4C and 4a, as shown by the full and dotted lines inFig. 2. The balls 5 may be of any suitableI diameter, but they arepreferably large enough to partially close or choke the passages leadingfrom the manifold to the cylinders, so that the gas may be drawn pastthe balls with sufficient force to efectually atomize or break it upbefore it enters the compression chambers. In order to further atomizeas well as to direct the flow of the gas towards one or the other sideof each passage, I provide an adjustable wing 7, which is preferablypivotally attached to each of the balls 5, by screws 7', the said Wingspreferably being disposed on the side ynearest the cylinders and beingmovable laterally to the extent shown in Fig. 4.

5 represents a plain sphere, Which is mounted upon a threaded rod 8, thelatter being adjustably supported by a screw-plug 9, which is preferablyreceived in a threaded opening 9', the latter being located about midwaybetween the arms el and da, and substantially in line axially with thevertical port-ion lb of the manifold (see llig. 2). The ball 5 ispreferably suspended in the hollow neck lh, as shown, and tends toreatomize the gas before it. enters the arms Ll and da. In order tofurther aid in breaking up the gas in the leg 4b, I sometimes in` sertin this funnel-shaped portion a loose roll of Woven-Wire lO, as shown inFig. 2,

The modification shown in Fig. 5 consists of applying to the spheres5'LL a plurality of radial wire legs 1I, preferably made of springmetal, which may be bent when applying the ball to a gas passage, andWhose tension tends to hold the ball in place, as shown. The legs Il arepreferably provided with serpentine feet, for increasing the frictionalcontacts of the parts.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

l. In reatomizers, the combination with the cylinders of an internalcombustion engine and an intake manifold, of a plurality of sphericalmembers disposed in the gas passages of the manifold, means foradjusting said members, and awing pivotally supported by each memberadapted for diverting the gas towards the opposite sides of saidpassages.

2, The combination with the cylinders of a. gas engine and the intakemanifold connected thereto, of a plurality of stationary sphericalmembers mounted in the gas passages of the manifold, two of said membersdisposed close to the intake port of the cylinders, the third memberbeing disposed in the down-leg of the manifold adjacent the juncture ofthe said leg with the arms of the manifold, the members adjacent theintake ports being adjustable for diverting the explosive mixturetowards the opposite sides of the intake port-s.

In testimony whereof I aliiz; my signature.
